Replacing the Toner Cartridge
The high yield toner cartridges can print approx. 8,000 pages
depending on coverage. When a toner cartridge is low, the LCD
shows Toner Low. *It is a good idea to keep a new toner
cartridge ready for use when you see the Toner Low warning.
• Press the front cover release button and open the front cover.
• Take out the drum unit and the toner cartridge assembly.
• Unpack the new toner cartridge and gently shake from side to
side several times to evenly distribute the toner.
• Pull off the protective cover.
• Put the new toner cartridge firmly into the drum unit until you
hear it lock into place. If you put it in correctly, the lock lever
will lift automatically.
• Clean the corona wire of the drum unit by gently sliding the
blue tab back and forth several times.
• Put the drum unit and toner cartridge assembly back in the
machine and close the front cover.
